Abstract
A new convenient procedure was developed for selective ortho-hydroxymethylation of phenols by reaction of paraformaldehyde with a mixture of phenol and orthoboric acid. The method is general for phenols containing no strong electron-withdrawing substituents; it allows preparation of o-hydroxybenzyl alcohols of high purity in a high yield.
